## Modified: We are subject to risks relating to acquisitions and joint ventures, and risks relating to the integration of acquired companies.

**Key changes:**

- Added sentence: "In addition, we may be unable to obtain necessary regulatory approvals or support for otherwise suitable business targets or joint venture opportunities, and we may be unable to obtain such regulatory approvals or support on the timeline or terms that we anticipate, if at all."
- Reworded sentence: "12 12 12 Table of Contents Table of Contents In addition, we may not be able to integrate successfully any businesses that we purchase into our existing business, and it is possible that any acquired businesses or joint ventures may not be profitable."

**Prior (2023):**

We expect to continue our strategy of identifying and acquiring businesses with complementary products and services, and entering into joint ventures, which we believe will enhance our operations and profitability. However, there can be no assurance that we will be able to continue to find suitable businesses to purchase or joint venture opportunities, or that we will be able to acquire such businesses or enter into such joint ventures on acceptable terms. Furthermore, there are no assurances that we will be able to avoid acquiring or assuming unexpected liabilities. If we are unable to avoid these risks, our results of operations and financial condition could be materially adversely affected. 14 14 14 Table of Contents Table of Contents In addition, we may not be able to integrate successfully any businesses that we purchase into our existing business and it is possible that any acquired businesses or joint ventures may not be profitable. For example, we have devoted significant management attention and resources to integrating the business and operations of Meggitt. We may encounter, or have encountered, the following difficulties during the integration process: •the consequences of a change in tax treatment, including the cost of integration and compliance and the possibility that the full benefits anticipated to result from the acquisitions may not be realized; •delays in the integration of management teams, strategies, operations, products, and services; •differences in business backgrounds, corporate cultures, and management philosophies that may delay successful integration; •the ability to retain key employees; •the ability to create and enforce uniform standards, controls, procedures, policies, and information systems; •challenges of integrating complex systems, technologies, networks, and other assets of the acquired companies in a manner that minimizes any adverse impact or disruptions to customers, suppliers, employees, and other constituencies; and •unknown liabilities and unforeseen increased expenses or delays associated with the integration beyond current estimates. The successful integration of new businesses and the success of joint ventures also depend on our ability to manage these new businesses and cut excess costs. If we are unable to avoid these risks, our results of operations and financial condition could be materially adversely affected.

## Modified: Our operations are subject to natural and man-made unexpected events that may increase our costs, interrupt production or our supply chain or otherwise adversely affect our business, results of operations or financial condition.

**Key changes:**

- Reworded sentence: "The occurrence of one or more unexpected events, including war, acts of terrorism or violence, civil unrest, fires, tornadoes, hurricanes, earthquakes, floods and other forms of severe weather in the United States or in other countries in which we operate or in which our suppliers are located could adversely affect our operations and financial performance."
- Reworded sentence: "The impacts of these unexpected events are difficult to predict but could have a material adverse effect on our business, results of operations or financial condition."

**Prior (2023):**

The occurrence of one or more unexpected events, including war, acts of terrorism or violence, civil unrest, fires, tornadoes, hurricanes, earthquakes, floods and other forms of severe weather in the United States or in other countries in which 12 12 12 Table of Contents Table of Contents we operate or in which our suppliers are located could adversely affect our operations and financial performance. Natural disasters, pandemics, such as the COVID-19 pandemic, equipment failures, power outages or other unexpected events could result in physical damage to and complete or partial closure of one or more of our manufacturing facilities or distribution centers, temporary or long-term disruption in the supply of component products from some local and international suppliers, and disruption and delay in the transport of our products to dealers, end-users and distribution centers. Existing insurance coverage may not provide protection for all of the costs that may arise from such events. For example, during the COVID-19 pandemic we experienced mandatory and voluntary facility closures in certain jurisdictions in which we operate. Furthermore, several of our customers temporarily suspended their operations and we experienced less demand for our products. Facility closures or other restrictions, as well as supply chain disruptions, did negatively impact and could in the future materially adversely affect our ability to adequately staff, supply or otherwise maintain our operations. The impact of unexpected events such as the COVID-19 pandemic are difficult to predict, but could have a material adverse effect on our business, results of operations or financial condition.

**Current (2024):**
